5.0.3:
This release features important security updates to Firefox.
We fixed a number of regressions from our switch to ESR 38 back in August and reduced keyboard layout fingerprinting to mention just some highlights.

A new stable release for Tor Browser is available from the Tor Browser Project page and also from our distribution directory.
This release features important security updates to Firefox.
Additionally, we included updated versions for Tor (0.2.7.6), OpenSSL (1.0.1q), NoScript (2.7) and HTTPS-Everywhere (5.1.1). Moreover, we fixed an annoying bug in our circuit display (circuits weren't visible sometimes) and improved our fingerprinting defense against MIME type enumeration.

Tor Browser 5.5, the first stable release in the 5.5 series, is now available from the Tor Browser Project page and also from our distribution directory.
This release features important security updates to Firefox.
On the privacy front we finally provide a defense against font enumeration attacks which we developed over the last weeks and months. While there is still room for improvement, it closes an important gap in our fingerprinting defenses. Additionally, we isolate Shared Workers to the first-party domain now and further improved our keyboard fingerprinting defense.
We made also progress on the usability side. First, by providing Tor Browser in another locale, Japanese. Additionally, by showing the changes in the new Tor Browser version immediately after an update and polishing our about:tor appearance. Last but not least we changed the search bar URL for the DuckDuckGo search engine to its onion URL.

Tor for Windows 5.5.4
This release updates firefox to 38.7.1. Mozilla decided to disable the Graphite library in this release and we are taking the same action: irrespective of the security slider settings the Graphite library won't be used for rendering fonts in Tor Browser 5.5.4.

v. 5.5.5
This release features import security updates to Firefox.
This release updates Firefox to 38.8.0esr. Additionally, we bump NoScript to version 2.9.0.11 and HTTPS-Everywhere to 5.1.6.
Moreover, we don't advertise our help desk anymore as we are currently restructuring our user support.

The Tor Browser Team is proud to announce the first stable release in the 6.0 series.
This release brings us up to date with Firefox 45-ESR, which should mean a better support for HTML5 video on Youtube, as well as a host of other improvements.
Beginning with the 6.0 series code-signing for OS X systems is introduced. This should help our users who had trouble with getting Tor Browser to work on their Mac due to Gatekeeper interference.
The release also features new privacy enhancements and disables features where we either did not have the time to write a proper fix or where we decided they are rather potentially harmful in a Tor Browser context.
On the security side this release makes sure that SHA1 certificate support is disabled and our updater is not only relying on the signature alone but is checking the hash of the downloaded update file as well before applying it. Moreover, we provide a fix for a Windows installer related DLL hijacking vulnerability.

v. 6.0.5 - Sicherheitsupdate!
This release features important security updates to Firefox including the recently disclosed extension update vulnerability. All users should upgrade as soon as possible.
Apart from fixing Firefox vulnerabilities this release comes with a new Tor stable version (0.2.8.7), an updated HTTPS-Everywhere (5.2.4), and fixes minor bugs.

v. 6.0.6

This release is updating Firefox to 45.5.0esr. Moreover, other components got an update as well: Tor to 0.2.8.9, HTTPS-Everywhere to 5.2.7, and OpenSSL to 1.0.1u.

Besides updating Firefox to 45.6.0esr which is fixing important security bugs we ship the latest Tor stable version, 0.2.8.11. HTTPS-Everywhere is updated as well (to 5.2.8) and we make improvements to our default obfs4 bridges
